ANDROIV ALFSON, OF COLUMBUS, OHIO, ASSIGNOE, BY DIRECT AND MESNE ASSIGNMENTS, TO HIMSELF, EDWARD W. TURNER, AND H. K. COVVAN,

ALL OF SAME PLACE.

IRON-GLAD VESSEL.

SPECIFICATION forming part of Letters Patent No. 277,972, dated May 22, 1883.

Application filed February 1, 1883.

To all whom it may concern:

Be it known that I, ANDROWALFSON, a subject of the King of Norway, residing at O- lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Iron-Glad Vessels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it IO appertains to make and use the same, reference 'beinghad to the accompanying drawings, and

to letters or figures of reference marked thereon, which form a part of this specification, and in which-- Figure 1 is a longitudinal section with the movable deck lowered. Fig. 2 is-a longitudinal section with movable deck raised. Fig.3 is a cross-section showing movable deck raised and armor-clad covers or decks open; Fig. 4, a

side elevation of one of the brackets; Fig. 5, a

view of the bottom of one of the brackets, showing arrangement of rack-bar.

My invention relates to certain improvements in iron-clad vessels, which I will now proceed to describe.

Similar letters of reference indicate like parts.

Referring to the drawings, A is the hull of thevessel; B, theinclined deck; 0, an opening in the top of said inclined deck.

D D are movable armor-clad decks or covers, which cover the opening G, thus rendering the vessel entirely armor-clad when said movable decks D D are closed.

E are metal brackets, to the top of which are secured the decks D D, said brackets E forming a support for the decks D D when the same are open. When the decks D D are closed the inner vertical arms of the brackets E, on opposite sides of the vessel, meet and may be secured to each other in any suitable manner to prevent the outward movement of the decks. To the under side of the arm E of the brackets E are secured rack-bars c, which extend half-way across said arm E and gear with the pinions F on the shaft G, said shaft G havingits hearings in the knees H, secured to the side of the vessel, by means of which (No model.)

pinions and rack-bars said brackets and decks are moved in or out, as desired.

I are openings in the side of the inclined deck B, through which the lower arms, E, of the brackets E pass.

I are slots in the inclined portion of the deck B, in which the arms E of the brackets fit when the decks D are closed.

K are cross bars or braces across the opening 0, upon which cross-bars the decks D rest when closed.

a are rollers secured to the knees H and in the bottom of the opening I, which engage with the smooth portion of the arm E.

a are rollers secured to the cross-bars K, and a are rollers secured to the under side of the movable decks D. 5

L is a chain-wheel on the shaft G, over which passes the chain L, which is connected with suitable machinery on the lower deck for operating the same. As many chain-wheels as are necessary can be used. sired to open or close the decks D motion is imparted to the shaft G by means of the chain L and chain-wheel L, and through the pinions F and rack-bars c to the brackets E. The decks can thus be moved in or out.

M is a movable Imrricanedeck, which can be raised or lowered. On said deck are the pilothouse, life-boats, &c.

N are posts or guides on which the deck M moves up and down, and by means of which it is held in position.

0 are chain-pulleys secured to the side of the inclined deck 3, over which pass the chains 0, one end of each of which is fastened to the deck M. The other, passing through to the lower deck, is connected with suitable machinery for operating the same.

a are rollers which operate against the posts N.

a are slots in the deck M, in which fit the cross-bars K when said deck M is raised.

P is the smoke-stack, which is made to telescope. The movable decksfi D are provided with an opening through which the smoke stack can project. When the vessel is not in action the decks l) D are opened and the deck When it is de- 70 M raised, as shown in Figs'.-2 and 3. When in action the deck M is lowered and the decks D D closed, as shown in Fig. 1. b are the gun-ports; 12, small lookouts.

. c is a bridge or gallery on each side of the vessel.

R R are ports, one or more of which are used as anchor-ports.

S is a pipe, through which runs the endless chain elevator S, for conveying ammunition from the hold to the gun-deck. At the top of the pipe S is an opening, 8, through which the ball passes to the conveyer-pipe S said conveyer-pipe being raised at the end nearest the elevator. Opposite each gun is an opening in said conveyer-pipe, which is closed by the hinged trough s.

Having thus fully described my invention, I claim- 1. In an armor-clad vessel, the combination of the horizontally-movable armor-clad decks. or covers D, brackets E, and means for operating the same, substantially as shown and described. 2. An armor-clad vessel having the inclined deck B, opening 0, cross-bars K, and knees H, in combination with the horizontally-movable decks D, having the brackets E and rackbars 6, the pinions F, mounted on the shaft G and gearing with the rack-bars e, and means for operating said shaft, substantially as shown and described. 1

3. An armor-clad vessel having the movable deck M, chains O', secured to said deck M, in combination with the posts N and chainpulleys O, and means for operating said chains, whereby the deck M can be raised or lowered,

as desired, substantially as shown and de-.

scribed.

4. In an armor-clad vessel, the combination of the movable deck M with the horizontallymovable armor-clad decks or-covers D and means for operating the same, substantially as shown and described.

5. A vessel having the inclined deck B, opening 0, cross-bars K, knees H, and horizontally-movable decks D, having the brackets E, and means for operating said decks D,

in combination with the, vertically-movable deck M and means for operating the same, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

ANDROW ALFSON.
